vserious damage `by explosives whilejat the same time preserving the safe against damaging influences of fire and water.V

The preferred embodiment-'of the inven-v tion possessing the characteristics'V abovev noted, is' illustrated in the accompanying drawings, forming part hereof, but, as will appeal te persons skilled in the art, the invention is capable of embodiments other than that specifically disclosed without departing vfrom the spirit thereof. The details of the emb'odimentrefcrred to will be lapparent from the specific description hereinafter acontainedf-when read in` connection with tliedrawings in which latter, Figure `lis a face view of one of the side walls cfa-conventional type of safe; and F ig. 2 is a fragmentany7 sectional view therethrough as indicated by/ the line www.

Referring more specifically to the drawings, wherein like reference characters designate corresponding .parts in'V the several views, A represents av steel side wall of theV safe, the same being provided with a. multitude of apertures B preferably of small diameter, say approximately one-half inch, conveniently? passing entirely through the wall, each aperture terminating at the front ina countersunk portion C constituting a the countersinks C for engagement by complementary exteriorly threaded'portions 4of tubes G constituting holders for valves or plugs vto lloe presently defined. This threaded connection is represented at E.

Each tube G has a flange Hl at its inner end adapted to abut the inner surface I of the wall A, it being observed that the tubes'- are introduced into the. apertures B from inside the safe, the forward ends of the tubes initially projecting therethrough as shown in dotted lines J, Fig. 2. After the`tt`1bes are vthreaded into engagement with the threaded bores constituted by the apertures B, the end K thereofis upset, after the manner of'a rivet intothe countersmk D, thus 'rmly fastening the tubes 1n place to constitute a permanent part of the wall A.

Near the forward end of each'tube G is a valve seat L in which a valve or plug M is adapted to tit, such fit being preferably a machine fit to avoid the use of-packing while at the same time affording a sealing engagement between the parts. Assisting in the retention of the valve or plug in place is a spring N passing through the tube G and adjustably connected through the medium ofthe threaded bolt O to a spider or screen P in turn abutting against a flange or other. suitable stop Q.' The normal .tendency of the spring'is to draw the valve or plug-M and the spider or screen P toward each other and against their respective seatsor stops L and Q.

Vhen the parts are properly assembled the exposed surface of tliewall A, offset endv K of the tubes and ends of the valves ofv plugs M' are'planed down in to iiush condition and polished to practically eliminate any appearance of the use' of or location4 of the valved vents or openings.

l have already referred tothe close-,fit1

ting engagementl of the valves in theirseats to preventthe admission of re or water to the compartment or compartments wit-hin the safe, and it will be appreciated `that. should an attempt be made. tio blow open the safe through the medium of explosives, .the gases .will pass through the 'screens or spiders Pland tubes G, thrusting the valves or plugs M 'outwardly from their pockets, and thereby opening the tubes `to the-eX- 'terior of the safe and permitting the gases to escape and relicvingthe pressure on the vinterior of the safe.

While l have shown'the use -of both the threaded engagement E, F and the upset-'- ting of the ends K of the tubes,'it is obvious that either one of thesev might be employed without the other .as `.may .be v found expedient. and inke'eping with the rconditions governing the use ofthe safe, etc.

AVV safe provided with avent opening, a valve thereimastop member, anda spring interposed between-the stop member and the valve constituting-the connection there-y between, saidY spring being located Within the vent opening, substantially as described. 2. A safe provided'with a vent opening,

a valve therein, avstop member, and a spring safe.

4. A s'afe provided With a vent opening,

a tube iixed therein, and a valve fit-ting said tube adapted to\o en to afford a passage through said tube, said tube having threaded engagement with .the body of the safe and having its opposite ends oset to prevent removal ofthe tube..

5. A safe provided With a vent'opening, a tube fixed therein, and a valve fitting said tube adapted to open to afford a passage through saidtube, said tube being offset to engage the body of the safe.

6. A safe provided with a Vent opening,

a tube secured therein, a Valve seat in said 8. A safe provided with a `vent opening,

a tube secured therein, a valve seat in sind tube, a valve engaging said seat, and means for maintaining the valve' in piace, said means comprising a spring engaging the valve and anchored in the tube, the anchoring means comprising a screen or spider engaging .the tube. In testimony whereof I aiiix my signature 'in presence of two Witnesses.
